Micro USB's improvement was reversing where the weak bits were. Now it's the cable that wears out, so when it does you just throw it out and buy a new one.
Attachment to the board is another thing entirely, it's all about having some sort of through hole pins to hold it in place (not all devices had that, some were purely surface mount), and good design. I think some devices had a tiny daughter board for the connector, to ensure that part could wiggle around a bit for stress relief.
